Go see Tbooth/The Telephone Booth. They have a case from Case-Mate, branded "naked" its fully encasing the palm pre, protecting the screen, and doesnt hinder the touchflow in ANY way, easy to clean, clear case, looks nice, doesnt hinder the gestures, the middle button, the slider doesnt get hindered, and it leaves all the plugs open and unclogged.
perfect case imo, only 34.99$. go see it for yourself, it form fits to the pre, like its an extra layer for the back and front. only flaw is that there was a manufacturing error i assume, and the cases all come with scratch/scrape marks on the back from what i've seen here in vancouver. But personally, still the best case. Keeps the phone safe in the pocket, and the screen safe at all times.
A must have for pre owners (unless you really want the touchstone charger, which i dont know why anyone would want it...)
(edit) and if you flirt well with the cashier you should get it for 29.99 like I did
